Mjolnir-X
Mjolnir-X is a configurable GNSS platform that can be configured for single-antenna positioning, dual-antenna heading or integrated GNSS/INS navigation. It accepts positioning boards from Trimble, Septentrio, Unicore, Bynav and other manufacturers, allowing its accuracy, update rate and orientation capabilities to be matched to the application. Integrated-navigation versions also provide automatic lever-arm calibration.
A built-in battery provides more than eight hours of operation, and a pre-configured CORS account allows correction services to be used with minimal setup. Configuration is handled through a web interface, with onboard storage and TF-card expansion available for data logging.
